MASSAGING INSTRUMENT.

EEGIXICATION forming part of Letters Patent No. 732,356, dated June 30,1903.

Application filed February 4, 1903.v Serial No. 141,871. (No model.)

` To all whom t may concern.-

Be it known that LBENJAMIN E. JosnPH, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in MassagingInstruments, of which the following is a specification.

The main object of my invention is to provide a simplified form ofpower-driven massaging instrument adapted for mechanically performingvarious operations which are useful for massaging treatments. Iaccomplish this object by the device shown in the accompanying drawings,in which- Figure 1 is a transverse section of a massaging instrumentconstructed according to my invention. Fig. 2 is a longitudinal sectionof the same along the line 2 2 of Fig. l.

In the construction shoWn the handle 3, of suitable form to be graspedby the hand of the operator, is rigidly connected to the middle part ofa hollow shank 4, which extends transversely of the handle 3. A shaft 7is journaled in the handle 3 and connected with a flexible shaft 5,through which rotation is communicated to the shaft 7 from a suitablemotor. (Not shown in the drawings.) Acrankpin 6 is rigid on the innerend of the shaft 7 and is disposed eccentrically on the axis of saidshaft, thus forming a crank for operating the mechanism Within the shank4. The shank 4 is provided with an aperture 8 in its side opposite theend of the shaft 7 for theV purpose of permitting access to the interiorof the shank 4. The aperture 8 is normally closed by a cap 9. One end ofthe shank 4 is closed by means of a plug 10, Within Which is mounted across-head 11. The crosshead 11 is slidable longitudinally of the shank4, butis confined against transverse movement. The outer end of thecross-head 11 has a screw-threaded aperture 13 therein for the purposeof removably securing thereto a mas. saging-head 12 of any desirableform. The inner end of the cross-head 1l has a transverse slot 14therein, Within which is seated one end of a pitman 15. The pitman 15 ispivotally connected to the cross-head 11 by the pivot 16, and the otherend of the pitman 15 is mounted on the crank-pin 6. An arm shank 4,which is opposite to the cross-head 11, said shank being provided with asuitable aperture 18, e Within which the arm 1-7 is seated. The arm 17is connected to the shank 4 by means of the pivot 19, Which is disposedin parallel relation to the shaft 7. The aperture 18 is closed by a cap20, through Which the arm 17 extends and which also forms a sleeve forretaining the pivot 19 in position. The outer end of the arm 17 is alsoprovided with a screw-threaded aperture 21,10 which a massaging-head 22may be' removably secured. The inner end of the arm 17 is provided witha cylindrical recess 23, disposed longitudinally of said arm.A A pitman24, titting therrecess 23, is seated therein and is longitudinallyslidable along said recess, but confined against `lateral movement withrespect to same. The pitman 24 is also journaled on the crank-pin 6.

The operation of the device shown is as follows: The shaft 5 is rotatedby a suitable motor and imparts such rotation to the crankpin 6, causingthe cross-head 11 to reciprocate longitudinally of the shank 4 throughthe action of the pitman 15. The arm 17 is simultaneously caused toreciprocate angularly on the pivot 19 through the action of the pitman24.

It will be seen that some of the details of the construction shown maybe altered Without departing from the spirit of my invention. Itherefore do not confine myself to :such details except as hereinafterlimited in VYthe claims.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A massaging instrument comprising a hollow' shank 5 a crank journaledin said shank on a transverse axis; a head mounted in one end of saidshank and longitudinally slidable therein; a pitman pivotally connectedto said crank and said headand adapted to cause said head to reciprocatelongitudinally of said shank through the rotation of said crank; an armpivotally mounted on a transverse axis in the other end of said shank;

a second pitman pivotally connected to said crank and suitably connectedto said arm to cause same to reciprocate angularly on said d 17 is.pivotally mounted in the end of the r ICO pivotal axis; said arm andsaid cross-head being adapted to have massaging-heads secured thereto;and means for rotating said crank, substantially as described.

2. A massaging instrument comprising a shank; a crank jonrnaled in saidshank on a transverse axis; an arm pivotally mounted on a transverseaxis in one end of said shank and adapted to have a massaging-headsecured thereto; a pitman connecting said crank with said arm, saidpitman being connected with said arm so as to be relatively slidablelongitudinallyr thereof but confined against movementlaterally thereofand adapted to cause said arm to reciprocate angular-1y on its pivotalaxis; and means for rotating said crank, substantially as described.

3. A massaging instrument comprising a shank; a crank jonrnaled in saidshank on a transverse axis; an arm pivotally mounted on a transverseaxis in one end of said shank and adapted to have a massaging-headsecured thereto; said arm having a longitudinal recess extending intothe inner end of same; a pitman seated in said recess and longitudinallyslidable therein, said pitman being connected with said crank and beingconfined against lateral movement in said recess and adapted to causesaid arm to reciprocate angularly on its pivotal axis; and means forrotating said crank, substantially as described.

Sgned at Chicago this 31st day of January, 1903.
